I do have another question.
I've recently been taking notice of uncut panels being offered here and there and see that, at least for the ones I've looked at, there is a white space, or "gutter", around the cards which made it possible to cut them nicely and leave a full black line framing the card.
This sad Bill Kilmer card has blue on the outside of the black line on 3 sides. It's the only one I have that doesn't have white. I also notice it is thinner, like the Unitas. Another tray card?
